The dental office is the second most-used dental office in the U.S. But the popularity of the office has seen a decline in the last two decades, with the average patient visiting only about 20% of the clinics over that period.

The decline is attributed in part to the rise of the Internet and the increased accessibility of dentists across the country.

According to the American Dental Association, the average American visits a dentist for a tooth extraction about once a week.

But a recent survey found that the number of visits to the dentist has been on a downward trend for more than a decade.

A new report from the University of Pennsylvania’s School of Dentistry found that visits to local dentists have been declining since 2009, according to the Associated Press.

The decline has been driven by changes in technology, according Dr. Peter J. Schaffer, a professor in the School of Dental Medicine.

“We’ve moved away from the concept of a dentist as a doctor who knows everything and then does things that are completely out of his comfort zone,” he said.

“It’s now become more about a dentist having to make a decision and figuring out what’s right for the patient.”

A recent report from Gartner found that dentist visits are on the decline in many parts of the U, including the states of Michigan, Wisconsin and Ohio.

The report said that the biggest culprits in declining visits are changes in the technology that is currently being adopted in many states.

For instance, more technology is being used in dental offices and in the dentistry itself, according the report.

In some cases, technology is becoming obsolete.

Dental offices are now able to take advantage of digital dental records and computerized systems to provide a more personalized experience.
